Tested briefly outdoors, seems to work fine. (Will do more testing later.)

The 90 degree connector is very handy, the wire does not stick straight out the side of the FR so it's easier to hold in your hand with the cable attached.

The purpose of this page is to give an overview on using external GPS antennas.

The connector for both the Neo 1973 and the Neo FreeRunner is the same, MMCX, but
the GPS chipset has been changed. Even though the antennas listed here will probably work on either Neo, they have been separated out according to what has actually been tested.

TTFF (Time To First Fix) and number of satellites locked in will vary greatly depending on the current conditions (the constellation of the satellites, terrain and buildings, and weather). To do a serious comparison test we would need to test all the antennas at the same time under known conditions. Currently this page will just tell you some antennas that have been found to function with the Neo FreeRunner and Neo 1973.
